The Search

S5 E13: The Ewings are unable to accept the fact that their father, Jock, could be dead, and J.R., Bobby, and Ray fly to South America to see the crash site and determine his fate. In South America the Ewing sons find an injured man at the crash site who tells them his small plane collided with a helicopter which crashed into the lake. Ray and Bobby dive into the lake and find pieces of a helicopter and evidence that their father was a passenger. It is J.R. who has the most trouble accepting the reality of his father's mortality.
